Patent Number: 7,613,010

Title: Stereoscopic electronic circuit device, and relay board and relay frame used therein

Abstract: A stereoscopically connected structure is made up of a first circuit board and a second circuit board which are mounted with other electronic components, and a relay board having a recess which is mounted with an electronic component and is provided with a lead-out wiring extending from the electronic component, and also having a land part to be connected with the lead-out wiring on one of the surfaces of the relay board that face the first circuit board and second circuit board. Thus the relay board can mount the electronic component thereon as well as connect the first circuit board and the second circuit board, thereby achieving high density mounting.
